CONCRETE FORM.

Application filed January ing the form members or rails in alinernent.

Another object is the provision of members secured to the end portionsof the rails or form members for the purpose of holding therails or form members in alinement, and also bracing and reenforcing the end portions of the rails.

v A further object is the provision of novel means for bracing the rails or form members to prevent lateral displacement thereof.

A still further object is to. combine the bracing means with the rail joint means, and a further object, in this connection, is to connect the rail joint means with stakes driven into the ground or sub-base to provide a simple and substantial form construction.

' It is also an object of the invention to provide a concrete form of the kind indicated providing for simplicity as well as eiiiciency.

in the joining together of the rails or form members and the bracing thereof.

With the'foregoing and other'objectsin view, which will be apparent as the description proceeds, the invention resides 1n the construction and arrangement of parts, as

metal and have the upright webs 8, base or bottom flanges 9 provided with upturned 15, 1926. Serial No. 81,397.

flanges 11, butt-he upper and lower flanges may be of the same or difl'erent widths. The rails are disposed end to end in alinement for defining the edge portion or side of a concrete road, sidewalk, curb, platform, or the like, while under construction, as well known in the art, with the flanges 9 and 11 disposed at the outer side of the webs 8. I

In carrying out the invention a vertical bar or memberlS is welded-riveted or otherwise secured to the web 8 of each rail at each end of the rail and has its upper and lower ends bent into eyes or loops 14 and 15 providing longitudinal dowel sockets bearing against the flanges 11 and 9, respectively. Said bars or members 13 stiffen and reenand strains of grading and finishing machines that travel on the rails. The flanges 11 are also supported at their ends by the sockets or eyes 14 toprevent said flanges being bent downwardly bythe wheels of gradingl or finishing machines passing over the rai s.-

When the rails are positioned end to end the upper andlower sockets 14 and 15 will register, and a dowel or pin 16 is inserted Ion gitudinally of the rails in each pair of registering sockets 15 while a dowel or pin 22 is inserted similarly in each pair of registering sockets 14, thereby maintaining the rails-in accurate alinement. I I

The bracing means are connected to the dowels 16 and 22. Thus, a brace or bar 17 is welded or otherwise secured to each lower dowel 16 at one end thereof and extends outwardly above the corresponding flange 9 and overt-he .flangc'or lip 10, and a stakesocket plate 18 is welded or otherwise secured on the outer or ,tree terminal of the brace 17 in lover-lapping relation therewith, and has a slot or opening 19 forming a socket for the passage of the stake 20 'that;is driven into'the ground or sub-base. .The stake 20, asshown,

is formed froln'a bar and-has alower pointed end, and a stop 21 is carried bythe stake near its upper end'to contact with the plate 18 and limit the downward movement of the stake.

As shown, the stake is disposed immediately outside of the flange or lip 10, and the brace 17 or plate 18 thereof bears on the edge of the flange 10. The brace 17 connecting the dowel 16 and stake 20 will prevent transverse displacement of the rails on the ground or sub-base. Furthermore, by driving the stake 20 down so that the stop 21 bears on the plate 18, this will assist in preventing the rails from tipping inwardly, inasmuch as the brace 17 will hold the outer edge portion of the flanges 9 down on the ground or subbase.

brace 28 is also connected to each of the upper dowels '22-, and comprises the overlap f stake socket plate 28 is welded or otherwise secured on the outer or free terminal of the brace in overlapping relation therewith, and has a slot or opening 29 providing a socket through which the stake 30 may be driven into the ground or sub-base. The stake 30 has stop 31 at its upper end to contact with the plate 28, and the stake 30 is;

similar to thest-ake 20, and said stakes may be used interchangeably. The brace 23 is inclined with its lower end outermost and connected to the stake, and with its inner end disposed immediately under the corresponding flange 11.

The braces 23 will brace the upper portions oi. the rails to'p'revent them from tilting either inwardly or outwardly, and it will be noted that the braces 17 and 23 connect the stakes with the lower and upper portions of the rails in order to securely brace the rails against lateral displacement either at the top or the bottom. "he rails have tendency to be displaced laterally, more especially to tip inwardly, when grading and finishing machines 7 travel on the rails, and by the provision of the "braces 17 and 23 this lateral displacement 01":

the 'rails is effectively eliminated. The lower braces 17 are connected with the ralls 1minediately above the flanges 9, while the braces vent the flanges 9 from swinging upwardly due to the tendency for therails to tilt inwardly. Thestakes 20 and 30 can be relativeshortinasnn'ich as they only extend a short ance above the ground or sub base when ven into place, so that the stakes may be somewhat shorter than stakes extending the full height (more or less) of the" rails.

in setting up the form, the r'alls orform the sockets so that the braces 17 and 23 are 05- set longitudinally, to prevent them from inter te'ring. After reasonable length of form has thus been arranged, the rails or form members are lined accurately, and the stakes are then driven through the plates 18 andaa into the ground or sub-base. By loosening the bolts or clamping elements 26 the braces 23 may be adjusted to adjust the ripper portions of the rails inwardly or outwardly into the desired line, after which the bolts 26 are tightened to maintainthe adjustment of the flanges 11. T1 desired, the stakes 20 are not driven into place until after the stakes 30 have been driven into place and the braces 23 adjusted, inasmuch as the base or bottom flanges 9 of the rails need little or no adjustment after the flanges 11 have been adjusted, said flanges 9 assuming proper position when the flanges 11 have been adjusted to the desired line.

The construction is economical and simple, and is rigid. The dowels and 22 being located at the base and tread flanges will keep the rails in accurate al ine'inent at the bottom and top, said dowels being spaced apart ve'rti Cally as far as possible. The shortest possible stakes may be used, so that they may be readily driven into place and withdrawn without being bent so readily as longer stakes, and the shorter stakes are also cheaper than longer ones. The braces and stakes prevent the rails from being displaced either outwardly or inwardly,- and the bracing and staking members are combined with the dowels or joint devices so as tosii'npli'fy the arrangement and increase the efficiency thereof.

Should it be desired to remove one of the rails 7, the dowels 16 and 22 at the ends there corresponding stakes have been withdrawn from the ground, and this will permit the rail to be lifted or moved laterally out vard, so that a truck may pass through the opening thus provided in the form. The rail may then be readily replaced. The dowels 16 and 22 and dowel sockets are of cylindrical form or circular in cross-section thus permitting the dowels to be readily inserted in the sockets and to turn therein, and the dowels provide pivot connections between the braces and rails, so that the dowels may be in serted in the sockets with the braces raised,

after which the braces may swing down into place. This also enables the outer ends of registering sockets of circular cross section, a

dowel of circular cross section inserted in said sockets and ada )ted to turn therein and 1 a. holding means connected, to SitltltlOWGl to turn therewith, v 2. A concrete form com risin form memu b bers having vertically spaced registering sockets, dowels inserted in said sockets, and
